If you are claiming tax credits, you will be sent a renewal pack, which will tell you how to renew your tax credits.
You must renew your tax credits by 31st July 2016 if your renewal pack has a red line across the first page and it says 'reply now'.
If you miss the deadline your tax credits payments will stop. You will be sent a statement and will have to pay back the tax credits you've received since 6th April 2016.
Further information on the process of renewing your tax credits is on the website below:
